Open Journal of Mathematical Optimization, 2021 The M-P (Moore–Penrose) pseudoinverse has as a key application the computation of least-squares solutions of inconsistent systems of linear equations. Irrespective of whether a given input matrix is sparse, its M-P pseudoinverse can be dense, potentially

A generalized inverse for graphs with absorption [PDF]
, 2016 We consider weighted, directed graphs with a notion of absorption on the vertices, related to absorbing random walks on graphs. We define a generalized inverse of the graph Laplacian, called the absorption inverse, that reflects both the graph structure ...

Incremental and Decremental Extreme Learning Machine Based on Generalized Inverse
IEEE Access, 2017 In online sequential applications, a machine learning model needs to have a self-updating ability to handle the situation, which the training set is changing.

Results on Resistance Distance and Kirchhoff Index of Graphs With Generalized Pockets
Frontiers in Physics, 2022 F, Hv are considered simple connected graphs on n and m + 1 vertices, and v is a specified vertex of Hv and u1, u2, … uk ∈ F. The graph G = G[F, u1, … , uk, Hv] is called a graph with k pockets, obtained by taking one copy of F and k copies of Hv and ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Outcomes in relapsed or refractory pediatric and AYA bone sarcomas remain poor, and the impact of early referral to specialized sarcoma centers on survival is unclear. Early centralization of care may improve local and systemic treatment quality, but evidence in this population is limited.

A Quaternion Matrix Equation Model with Application to Color-Image Watermarking
MathematicsWe study two coupled two-sided quaternion matrix equations sharing an unknown. Because the map X↦AXB is real-linear but not generally quaternion-linear, an order-preserving real representation converts the problem into one real system. It yields an exact

The Beta Generalized Inverse Weibull Geometric Distribution
Pakistan Journal of Statistics and Operation Research, 2017 A new six-parameter distribution called the beta generalized inverse Weibull-geometric distribution is proposed. The new distribution is generated from the logit of a beta random variable and includes the generalized inverse Weibull geometric ...

On sparse reflexive generalized inverse
Operations Research Letters, 2018 We study sparse generalized inverses $H$ of a rank-$r$ real matrix $A$. We give a construction for reflexive generalized inverses having at most $r^2$ nonzeros. For $r=1$ and for $r=2$ with $A$ nonnegative, we demonstrate how to minimize the (vector) 1-norm over reflexive generalized inverses.
